Description
Technical field
The utility model relates to rainfall runoff characteristic monitoring device, is especially applied to the device of urban road inlet for stom water runoff water flow characteristic monitoring.
Background technology
At present, the waterlogging that causes of pavement runoff and pollution of area source problem have been paid close attention to widely and have been paid attention to.But the firsthand data of the pavement runoff water yield, water quality characteristic still lacks very much, for the application of pavement runoff basic research and control technology causes obstruction.This because rainfall belongs to contingency, randomness event, is not easy to monitor the complete runoff water yield, water quality process on the one hand; The more important thing is, the monitoring of pavement runoff removes pipe laying flowmeter, and outside artificial volumetric method monitoring, there is no better method, but the cost of pipeline flowmeter is higher, large-scale flow monitoring is very uneconomical, and also comparatively dangerous at town road enterprising pedestrian's work flow monitoring.
Utility model content
Lack the deficiency of economic, effective, safe monitoring facilities to overcome the monitoring of existing pavement runoff, the utility model provides a kind of urban road inlet for stom water runoff characteristic monitoring device.
For achieving the above object, the utility model comprises following technical scheme:
A kind of urban road inlet for stom water runoff characteristic monitoring device, it comprises the diversion trench 1, triangle weir notch 4 and the water-level gauge 6 that are arranged on inlet for stom water 12 inside; Wherein, diversion trench 1 is arranged in the walling crib under inlet for stom water rain grate 9; Below diversion trench outlet 3, triangle weir notch 4 is set; Water-level gauge 6 is vertically placed in triangle weir notch and tests SEA LEVEL VARIATION.
Device as above, preferably, described diversion trench 1 is located on inside inlet for stom water upper end, its outer peripheral sidewall edges close overlap joint inlet for stom water walling crib, its inner circumferential sidewall 2 while be provided with opening as diversion trench outlet 3, this diversion trench bottom surface tilts towards diversion trench Way out.
Device as above, preferably, described triangle weir notch 4 is rectangular channel, an one sidewall has triangular-notch weir 5, arranges adjusting pole 7 bottom it.
Device as above, preferably, the angle of described triangular-notch weir 5 is 30 ° ~ 90 °, and the width of triangle weir notch 4 is less than 33cm, and the height of adjusting pole 7 is greater than the rain pipe internal diameter be arranged at for draining bottom inlet for stom water.
The beneficial effects of the utility model are: can collect pavement runoff the imports inlet for stom water water yield in source completely, accurate test is confluxed discharge process, and cost is low, it is few to safeguard, do not affect vehicle pass-through after rain grate covers, the runoff overall process monitoring in inlet for stom water in flood season basin can be advantageously used in.

Embodiment
Embodiment 1
As shown in Figure 1 to 4, in a kind of preferred implementation of the present utility model, this urban road inlet for stom water runoff characteristic monitoring device comprises the diversion trench 1, triangle weir notch 4 and the water-level gauge 6 that are arranged on inlet for stom water 12 inside.Diversion trench 1 is arranged in the walling crib under inlet for stom water rain grate 9; Below diversion trench outlet 3, triangle weir notch 4 is set; Water-level gauge 6 is vertically placed in triangle weir notch and tests SEA LEVEL VARIATION.
Diversion trench 1 is located on inside inlet for stom water, and its outer peripheral sidewall edges close overlap joint inlet for stom water walling crib, prevents runoff seepage; Its inner circumferential sidewall is while be provided with opening as diversion trench outlet 3; Diversion trench bottom surface tilts towards diversion trench Way out.Runoff flows, from the outlet that diversion trench is unique in the region that diversion trench inner circumferential sidewall (fair water fin) 2 and outer peripheral sidewall surround---and diversion trench exports 3 and discharges.
Below diversion trench outlet 3, triangle weir notch 4 is set, receives the runoff that diversion trench imports.Triangle weir notch 4 is rectangular channel, and an one sidewall has triangular-notch weir 5.Adjusting pole 7 is set bottom triangle weir notch 4.The bottom of inlet for stom water 12 arranges the rain pipe 8 for discharging rainwater.Discharge process is drawn by the stage discharge relation of triangular-notch weir.
Inlet for stom water 12 is brick flat grate formula list gutter inlet grating (cast iron walling crib), and inside inlet for stom water, the length × wide of well head is 68 × 38cm, and the degree of depth is 90cm; The length of triangle weir notch 4 × wide is 60 × 33cm, and the degree of depth is 45cm; The angle of triangular-notch weir 5 is 45 °, and lower end is 15cm to the height of triangular-notch weir bottom land; The internal diameter of rain pipe 8 is 20cm, and the length × wide × height of adjusting pole 7 is 55 × 30 × 30cm.
As shown in Figure 4, during actual monitoring, rain grate 9 is flat, and makes not affect vehicle pass-through.First pavement runoff by rain grate 9, confluxes and enters diversion trench 1, and runoff is guided to diversion trench outlet 3 by diversion trench 1, imports triangle weir notch 4 subsequently.In triangle weir notch 4, the water yield is discharged by 45 ° of triangular-notch weirs 5, finally enters rain pipe 8.The water-level gauge 6 installed in triangle weir notch 4, tests and record trough inner water position.By the stage discharge relation of triangular-notch weir, draw inlet for stom water discharge process.
Above embodiment is only for illustration of the utility model; and be not limitation of the utility model; the those of ordinary skill of relevant technical field; when not departing from spirit and scope of the present utility model; can also make a variety of changes and modification; therefore all equivalent technical schemes also belong to category of the present utility model, and scope of patent protection of the present utility model should be defined by the claims.
